Purpose
This study examined factors influencing patient safety nursing activities in integrated nursing care units. Methods: A survey was conducted with 134 nurses from hospitals (100~300 beds) in Busan using self-administered questionnaires (August 17–September 15, 2024). Data were analyzed using descriptive statistics, Pearson correlation, and multiple regression analysis. Results: The mean score for patient safety nursing activities was 4.31±0.55. Positive correlations were found with grit, teamwork, communication, and patient safety culture awareness. The predictor variables explained 46.0% of the variance in patient safety nursing activities. Significant factors included communication (β=.31, p=.032) and leadership (β=.29, p=.035) within teamwork, incident reporting frequency (β=.24, p<.001) within patient safety culture awareness, and experience in patient safety education (β=.17, p=.018). Conclusion: The findings of this study highlight the importance of enhancing teamwork, particularly in leadership and communication, and creating a safety culture that promotes incident reporting and education to strengthen patient safety nursing practices. Improving patient safety training, developing systematic evaluation and feedback mechanisms, and establishing structured support systems through campaigns and workshops will boost staff involvement and elevate the quality of patient safety practices.

Purpose
This study aimed to identify factors influencing communication competence among hospital nurses. Methods: The participants were 136 nurses working at five general or tertiary hospitals with over 100 beds in Busan, Ulsan, and Geoje Island. Data were collected using structured self-report online questionnaires from July 18 to August 31, 2023. The data were analyzed using descriptive statistics, the t-test, one-way analysis of variance, the Scheffé test, Pearson's correlation coefficients, and stepwise regression analysis using IBM SPSS version 25.0. Results: Self-awareness (β=.43, p<.001), a relationship-oriented organizational culture (β=.34, p<.001), working in a surgical ward (β=.19, p=.003), communication efficacy (β=.17, p=.011), hierarchy-oriented organizational culture (β=.16, p=.011), and working in a special unit (β=-.14, p=.023) were factors that significantly influenced nurses' communication competence. The model explained 52% of the variance in communication competence (F=28.43, p<.001) Conclusion: To improve communication competence in hospital nurses, healthcare institutions should provide learning opportunities to improve nurses’ self-awareness and communication efficacy. It is also essential to establish rules and order within a hierarchy-oriented organizational culture, while simultaneously promoting a relationship-oriented organizational culture based on trust and respect among colleagues.
